A ,:vonstrui-tion ha ring the` :sanne object in ric-w is (lis-clonal auil claimed in nl v latcnt No. 1,0%,049 of Fnhrnanv Q4, 1314. An aili'antagc in the proscnt construction. howoror, is in that the extensions of lho slanilarfl arc Hm'nrcil Clircctly to thc jack standard. thiI wcm-ing moans lining of' wry siinplo forni. 1y this nn'ans sm'eralA of' thc parts of thc (larice hore'toforc riforroil to havo haan climinalcrl without ilotraf-tiingr in an)v lnanncr l'roni tho ofoctivcnosa of tho ilcviw. ln ag'hlilion, l haw provifloil a' hracirofl :ula )lod lo ho sorurcil to thc stanllarrl ainl to i-xlonrl lo a ligliil portion of tho f'ar u hicltlghang supported, in orllcr to act aS a hraco angl ohviale theY possil'lity of upsetting' or ovcihahmcing the jack.

The invention will ho moro rcrnlilyY iunior'- stood by refcroncc to thc aoconipanyinfj;l drawings, whereinlligurc l is an elevation of a jack con Structed in accordance with inyiinvcntion, the same lining shown in aasooiation with a, portion of an automohilc; Fig. 2 is a plan View of the jack; Fig. 3 is a sirio nlm-ation of thc construction as shown in Fig. l; vicw, lallowing in ilctail ono of the. clamps, thc main :unl cxtcnsion Standards hcing shown in Suction, aml Fig. 5 is a section on the lino 5---5 of Fig. 4.

ln the drawings, it will hc accu that thc jack of my invention comprisos a triangular' frame 10, having Whccls 11 at throo corners thereof. At tw'o of the corners I provide threaded standards 12 adapted for simultaneous actuation by the shaft 13, miter Specification of Letters Patunt.

'Hoax-vcr. whon itis dosirml lo lift` thc hotlyr ol tho` autoniohilc wilhonl, (ha axlc, it is 1n-rvsaa|.\'Y to provide an oxlvnaion lo tho standard l2 ankl thisl I avmniplh in tho following manner. As lluhw ioos whirh aro applied to cach ol thc aiaialarila aril iluplicalus l will loscrihc hat omthaw-ol'. brac-kut nwmhcr ll' is prorhhwl with a Vertical apprtllro lfil anfl a notrhcrl i'i-rtical flange lflsurrolulcling the apvrluriat tho upper cnil. fithin this apirlln'c an cxLi-nsion standard 20 is accomnaalaiwl, thc oppor cnil of which is surniouufofl h a fool 21. similar to thil foot 1h, anil allaptcil to cn'g'agc a portion of' thc franal or horlyof an aatomohilo as shown in Fig. 1. As a moans for adjustingY tho hcight o1" a Hlanilaril anrl hohling tho sami'` iu ail ixustvfl position. l proriilc aporturcs 22 in thc i-xtcnsion standard and pass a pin. 23 through om` of.' Haiil :im-rtums,4 the pin lying,r in thc notchcs 24 forlnorl in thc .vortical langc 19. As a lucana for socnrim..r [hc hrackct inolnhor to thi' lhrcadcil stalnlaril. l proriile a rlainp including thu arm 25, pirotml at 26 to .in apcrturwl lug on thc ranting' 17. tho clamping' alcnnnt coluplfising.;r a holt 27,'pirolwl at. 'H toanolhor portion of iho'rasting :unl ailaptoil to :swungT into vngagvna-nt with thc forhoil uml of thc arm 3.7 anil hc rigidly' hohl hy moans of a nnt 2f). A lhrcarh-l apcrturc ia provhhal hotwoiu thc hraclwt nicmhcr anrl thc arm, one half of saiil aporturo boingr in nach oi' said nicmhors. 'lhf` pitch of thil thrcails in this.r aportnro is tho sama as that of thc thriads on the standar-fl 12. 'l`lna'cforc, thc hrachols mayr lw cng'agorl with thc slamlaril and fawunf.,r into thc propvr position` whereupon tht` clamp is tightcnvel :unl tho hrack'cts hohl rigriilly in a fivwl position.

As it f rcqumltly is (li-Hirahlo to elevate a car hotly and tharcaftcr Naoom the axle and whcvls,A as woll :is moro the car about after harin;r rcinmil thc axlus and whccls, I proviilc moans which tomi to obviatc thoposshility of tipping,r over thc jack. 'lo this und 'l' prorhlc a bravo lod 30, havingr a. clamp 31 at one ondv and a hook 32 al; thc other. ond. 'lho hook 32 is adaptod to engage an aportnrcd'car 33 on thc bracket member 17, while thoolam'p 31A is adapted to engage the running board 34, or some similar part 0f the automobile body. By thisl means the danger ol tipping the jaelc is obviated.

Anailvantageinthe presenteonstriwtion is in that the standard is ixeil to the threaded standard ol lhejael; in the most ronrenient manner without regard to the other standard or without regard to thi` ditferential rating or other portions of the axle. The coiislruetions has manyy advantages which wil be apuirent to those skilled in the art, and it is bivious that inodilieations may be triade therein. Such modifications as are within the scope of my claims 1 consider within the spirit of my invention.

By reason of the construction of the clamp and the fact that the support for the standard :ZOis laterally oliset with relation to the axis ol the screw threaded standard 1Q, the space between adjacent standards 2G mayI be adjusted by swinging the clamps on the threaded standards. The position of the feet il "s determined by rotating the standard Z0 in its socket.

I claim:

i. In a jat-k, the combination ol' a` threaded standard, a bracket adapted to be clamped to the threaded portion of said Standard, and u second Istandard mountedinsaidbrzuflofl with means for vertically adjusting,` said last nieu tioned standard, substantially as described.

L. In a jack, the. combination of a threaded standard, means for raising and hovering: said standard, a Clamp adapted to ei'igage the threaded portion of said standard, au apertured extension from said Clamp, and a seeond standard mounted in said aperture with capacity for vertical adjustment, sul stautiallyv as described.

3. In a jack, the combination of a threaded Ystandard, a bracket having a vertical aperture, a clamp associated with said bracket and adapted to engage the threaded portion of said standard, an extension standard adapted toI occupy the aperture in said bracket, and a brace-rod extending from said bracket to the article to be supported by said jaek, substantially as described.

4. In a device of the class described, the Combination ,of a casting lniviirr a vertical aperture therein and provided with an apertured lug, an arm hinged to'said lug, screw` means for engaging and holding' said arm., a threaded aperture being provided be tween Huid extension and said arm, one-half ol' said threaded aperture being in each of said portions, :said threaded aperture being adapted to engage the threaded stalulald of' a jaeli, and au extension standard adapted to occupy the first named aperture iu said casting, substantially as ilefierihed.

5. vIn a device of the class described, the roinbinatioa of a member haring a vertical aperture, an apertnred ear and an apertured lug, a clamping member associated with said a pertured lug whereby said member may be attached to a vertically adjustable portion of a jack, and a brace-rod adapted to be seeured to said apertured ear, su istantially as described.

(3. In a jack, the combination ot a thread ed Standard. a bravket adapted to be clamped to the threaded portion ol' said standard. and a sei-mid standard mounted in said bracket u ith means'. for `vertically adjusting said last mentioned etandaril. sai-fl bracket being ro tatable about said threaded Standard as an axis, soif-stantiaily as. described.

'i'. In a jai-ii, the combination ot' a pair ot `dandards. mean. for rertiially artiest-ing said standarde, :i pair of brackets, one of whirh. is alla'1 ed to be s* -uieil to the. threaded portion of each o .aid standards, Said brackets being eaeh provided with a wrtieal api-:ture which is eccentric. to the point of attaelunent of the bracket to said threaded standard, said braelets being mounted for rotation on the standard, and extension standards inonutrd in the veitieal apertures of' said brachen; and prorided with means for staining' a wrti ai adjustment of said extension standards: relative to said brackets, the arrangement being sneli as to pro; \ide for ailinsting said extension standards toward and from each other' by rotating one thereof about the thraded Standard to whirh it is connected.` snbstantiaily as de scribed.
